BACKGROUND ART

A quinoline derivative represented by the formula (I) or apharmaceutically acceptable salt thereof or a solvate thereof(hereinafter referred to as quinoline derivative (I)) has been known tohave a potent angiogenesis inhibitory effect (Patent Literature 1) and ac-Kit kinase inhibitory effect (Patent Literature 2) and to be useful asa preventive or therapeutic agent against various tumors such as thyroidcancer, lung cancer, melanoma and pancreatic cancer, and as anmetastatic inhibitor against these tumors:

wherein, R¹ is a hydrogen atom, a C₁₋₆ alkyl group or a C₃₋₈ cycloalkylgroup; and R² is a hydrogen atom or a methoxy group.

However, the quinoline derivative (I) has been found to degrade underhumidifying and warming storage conditions when formulated into apharmaceutical composition. In addition, when the pharmaceuticalcomposition absorbs moisture, dissolution of the quinoline derivative(I) from the pharmaceutical composition that is an active ingredient maydelay because of gelation on the surface of the composition. In order toovercome these problems, a pharmaceutical composition which includes thequinoline derivative (I), (1) a compound, a 5% (w/w) aqueous solution orsuspension of which has a pH of 8 or more, and/or (2) silicic acid, saltthereof or solvate thereof has been developed (Patent Literature 3).
